To @ZZ whom it may concern:

Be it known that we, ARTHUR C. HUIDE- KOPER and LUo HoUzn, of Meadville, in the county of Crawford and State of Pennsylvania, have invented certain new and useful Improvements in- Apparatus for Making Fuel- Gas; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and .to the letters of reference marked thereon, which form part of this speciiication, in which- Figure l represents a vertical sectional view of our apparatus complete. Fig. 2 is a top View showing the injector applied thereto.' Fig. 3 'is.a vertical sectional view ofthe apparatos in connection with the boiler-furnace, also shown in section.

This invention relates to certain improvements in apparatus for manufacturing and burning gaseous fuel; and it has for its objects to provide for the production of a gaseous fuel from petroleum, superheating steam or compressed air, heating of air, and finally mixing the gaseous currents and burning the same, as more fully hereinafter specified.

The above-mentioned objects we attain by the means illustrated in the accompanying drawings.

The letter A indicates a vertical shell or casing, which is preferably cylindrical in horizontal cross-section; and B, an interior concentric chamber, the lower part of which constitutes the lire-pot of the apparatus.

b designates an opening below the grate in chamber B, through which air is admitted to the fuel for maintaining combustion.

The walls of the concentric shells or chambers are constructed, preferably, of some nonheat-conducting material, such as nre-brick, asbestus, or the like, and may be held in place by metallic encircling cylinders, as shown. Between the two concentric chambers is an annular space, which is divided into upper and lower compartments by an annular partition, C, which extends around the furnace just above the fire-pot of the same.

The letter D indicates a pipe leading from the steam space or dome of the boiler of the engine or from an air-compressor to a coil of pipe, E, encircling the dre-pot and leading off outwardly through the casing to an eductionpipe, F, and pipes F', which enter the pipe K obliquely. The upper space between the outer and inner shells of the initial furnace forms an air-chamber, which receives its blast or draft of air through the valved opening G and communicates with exit-pipes H, leading to the pipes F, and through the steam-pipes F into the pipe K, whereby the gas generated from the heated petroleum or oil may be carried over to the combustion-chamber L.

The letter M indicates a tube which enters through'a stuffing-box, N, at the upper end of the inner chamber of the generator. To the lower end of said tube is secureda series of connect-ed perforated radial arms or a perforated box, P, through which the petroleum may be dropped. The said tube at its upper end is provided with a funnel, It, which receives the petroleum from a pipe, S, extending over it. -The said tube is also provided with arms T, by which it may be turned from time to time, so as to distribute the fluid equally onto the fuel below.

The letter V indicates a valve controlling an opening leading to the inner cylinder, through which solid fuel may be supplied. This valve may be controlled by a cord or other mechanism, which, however, forms no part of the present invention.

The re being kindled in the fire-pot the same as in an ordinary stove, fuel is supplied from time to time through the Valved funnel W'. The petroleum is then permitted to enter in properly-regulated quantities, and steam from the steam-space of the boiler or compressed air is let in the coil around the lirepot, which becomes superheated and passes under strong pressure through the pipes F F into the pipe K, carrying the heated air from the air-chamber and gases from chamber B with it into the combustion-chamber Lof the boiler, where the combined gases are burned.

Patents have heretofore been granted for generating gas by dripping hydrocarbon oils over highly-heated refractory material; but our invention differs from them in the employment of steam toproduce a draft through the tire-pot, and jets ofair, in conjunction with the gases, to support combustion in the combustion-chamber of the boiler, resulting in the ICO advantages of increased heat, economy of material, and the more convenient management of the burning gaseous fuel. Revolving distributing-feeders operating on the principle of the Barkers mill are old; but our invention differs from such distributers in having means for turning the same by hand, thus securing the advantage of a positive movement independent of the low of petroleum.

The outer walls of the chamber A are lined with asbestos or other non-conductor of heat to prevent loss of heat.

As will be seen, the novelty of our inven tion consists in the vaporizing-chamber, the heating-chamber, air-coil surrounding the inner wall of the lower chamber, and the pipe which is connected to the vaporizing-chamber and combustionchamber, and forward air-eX- haust; also, in the arrangement of the concentric vessels forming vaporizingchambers, the space between the two vessels divided into upper and lower superheating-spaces, the air and steam pipes, and the pipe leading from the gas-generating chamber and the combustion-chamber of the boiler.

Having described our invention, we claiml. The combination of two concentric external and internal vessels, forming a vaporizing` chamber, the space between the two vessels divided into upper and lower heating-chambers, the upper chamber communicating with an exhaust chamber, and the superheating steam or compressed-air coil surrounding the inner wall ofthe lower chamber and leading to a pipe which is connected to the vaporizingchamber and a combustion-chamber and forming au exhaust, whereby the gases, with air, are forced into the combustion-chamber of the boilerfurnace and burned, substantially as specified.

2. The combination of the two concentric vessels forming the vaporiZing-chambers, the space between the vessels divided into upper and lower superheating-spaces, the air and steam pipes, and the pipe leading from the gas-generating chamber to the combustion` chamber, and the combustion-chamber of the boiler, whereby the gases are mixed prior to burning, substantially as specified.

In testimony that we claim the foregoing as our own we afxour signatures in presence of two witnesses.
